We've had the "How many CDs do you own" type threads but here's a slightly different slant on it.

So I don't have an mp3 player (yet) and I got pissed off with lugging CDs backwards and forwards to my office to listen to at work. I decided to rip my CDs to my laptop to get round this. I've got about a third of the way through and I have 73 hours of music in my media library already, so using a bit of extrapolation that equates to well over 200 hours of music in total. That sounds a hell of a lot to me and I know my CD collection is quite modest compared to some of you DiSers. OK, this is turning into an oR-esque thread so I'll get to the punchline:

For those of you who've bothered to copy their CDs to your PC, how many hours of music do you have?
